Description
Wärmeaustauscher fUr ErdwärmenutzungHeat exchanger for geothermal energy use
Die Erfindung bezieht sich auf einen Wärmeaustauscher zur Nutzung der Erdwärme für Heizzwecke.The invention relates to a heat exchanger for use geothermal energy for heating purposes.
Derartige Erdwärmeaustauscher werden insbesondere beim Einsatz von Wärmepumpen gebraucht, da andere Wärmequellen entweder einen ungtinstigen Temperaturverlauf haben (AuBenluft), selten sind (Oberflächenwasser) oder aufwendige Anlagen und Wartungen erfordern (Grundwasser).Such geothermal heat exchangers are particularly useful when using Heat pumps needed because other heat sources either have an unfavorable temperature profile have (outside air), are rare (surface water) or complex systems and maintenance require (groundwater).
Erdwärmeaustauscher sind bekannt als mäanderförmig horizontal etwa 1 bis 2 Meter tief im Erdreich verlegte Rohrschlangen (siehe z.B. v.Cube, H.L. und F.Steimle: Wärmepumpen, VDI Verlag 1978 Düsseldorf sowie Kirn, H. und A.Hadenfeldt: Wärmepumpen, Verlag C.F.MUller 1976 Karlsruhe).Geothermal heat exchangers are known as meandering horizontally approximately Coiled pipes laid 1 to 2 meters deep in the ground (see e.g. v.Cube, H.L. and F.Steimle: Wärmepumpen, VDI Verlag 1978 Düsseldorf and Kirn, H. and A. Hadenfeldt: Heat pumps, Verlag C.F.MUller 1976 Karlsruhe).
Die Verlegung dieser Rohrschlangen erfordert allerdings umfangreiche Erdarbeiten, die besonders bei bebauten Grundstücken mit angelegten Gärten zu hohen Kosten führen. Ein Nachteil der horizontal verlegten Rohrschlange ist, daß im Winter nach längerem Einsatz die Erdschicht oberhalb der Rohrschlange durch Wärmeabgabe an den Wärmeaustauscher und an die Erdoberfläche stark abkühlt. Der Wärmeaustauscher kann dann nur noch den tieferen Erdschichten Energie entziehen. Der Erfindung liegt die Aufgabe zugrunde, einen Wärmeaustauscher mit weniger Aufwand und höherem Nutzen ins Erdreich einzubringen.The laying of these pipe coils, however, requires extensive work Earthworks that are too high, especially in built-up plots with landscaped gardens Lead to costs. A disadvantage of the horizontally laid pipe coil is that in winter After a long period of use, the layer of earth above the pipe coil through heat dissipation on the heat exchanger and on the surface of the earth cools down considerably. The heat exchanger can then only extract energy from the deeper layers of the earth. Of the The invention is based on the object of providing a heat exchanger with less effort and to bring greater benefits into the ground.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß entweder Je zwei Rohrstangen oder Rohrstangen mit zwei Fließkanälen senkrecht in das Erdreich gedrückt werden, die unten miteinander verbunden, aber gegenüber dem Erdreich geschlossen sind. Dadurch kann Sole in einem Rohr oder Fließkanal nach unten und im anderen wieder nach oben fließen. Geeignete Anschlußstücke führen die Sole zur Wärmepumpe.The object is achieved according to the invention in that either two each Pipe rods or pipe rods with two flow channels pressed vertically into the ground are connected to each other at the bottom, but closed to the ground are. This allows brine to go down in one pipe or flow channel and in the other flow up again. Suitable connecting pieces lead the brine to the heat pump.
Die Vorteile bestehen darin, daß diese Erdwärmeaustauscher ohne große Erdarbeiten und ohne Zerstörung in angelegten Gärten installiert werden können. Bei genügender Länge der Wärmeaustauscher wird die Wärme von tieferen Erdschichten genutzt, die vom Klima weitgehend unbeeinflußt sind und die Energie von allen Seiten dem Wärmeaustauscher zuführen können. Die Wahrscheinlichkeit, Erdschichten von oberflächennahem Grundwasser mit hoher Wärmeleitung und Wärmekapazität zu erreichen, ist groß. Beim Ausfall eines Wärmeaustauschers kann das Element relativ leicht herausgezogen, repariert oder ersetzt werden.The advantages are that these geothermal heat exchangers without major Earthworks and can be installed in landscaped gardens without destruction. If the heat exchanger is long enough, the heat is removed from the deeper layers of the earth that are largely unaffected by the climate and the energy from all sides can feed the heat exchanger. The likelihood of strata of the earth from near the surface Reaching groundwater with high conduction and heat capacity is great. At the Failure of a heat exchanger can cause the element to be pulled out relatively easily, repaired or be replaced.
Ausführungsbeispiele zeigen Bild 1 bis 3.Examples are shown in Figures 1 to 3.
Bild 1 zeigt zwei Rohrstangen 1 aus Metall oder Kunststoff mit kreisförmigem, dreieckigem oder rechteckigem Querschnitt nebeneinander angeordnet und durch Schweißen, Löten oder Kleben miteinander verbunden. Unten ist durch Schweißen, Löten oder Kleben ein Formteil 2 eingesetzt, das die Öffnungen der beiden Rohre miteinander verbindet und sie gegen das Erdreich schließt. Oben sind Anschlußstücke 3 für Schläuche eingesetzt.Figure 1 shows two pipe rods 1 made of metal or plastic with a circular, triangular or rectangular cross-section arranged side by side and welded, Soldered or glued together. Below is by welding, or soldering Adhere a molded part 2 is used, which connects the openings of the two tubes with one another and closes it against the ground. At the top connection pieces 3 are used for hoses.
Bild 2 zeigt zwei koaxial angeordnete Rohre 4 und 5 aus Metall oder Kunststoff, von denen das äußere unten verschlossen ist (6 und 8) und das innere nicht.Figure 2 shows two coaxially arranged tubes 4 and 5 made of metal or Plastic, of which the outer one is closed at the bottom (6 and 8) and the inner one not.
Das innere Rohr 5 kann auch durch den Anschlußschlauch gebildet werden. Das Anschlußstück 7 hat die Form eines T-StUckes mit verschiedenen Durchmessern und wird durch Kleben oder Pressen (bei der Verwendung von Gummi) mit den Rohren 4, 5 und 9 verbunden. In Bild 2a ist das untere Rohrende durch eine Quetschdichtung verschlossen. Diese Dichtung kann in ein schon in das Erdreich gedrücktes Rohr montiert werden und ermöglicht so das Eindrücken eines offenen Rohres mit weniger Verdrängungsarbeit. Das Erdreich im Rohr wird durch Heben oder Spülen entfernt . Das Rohr 4 kann auch durch eine Vergußmasse unten abgedichtet werden. The inner tube 5 can also be formed by the connecting hose. The connection piece 7 has the shape of a T-piece with different diameters and is made by gluing or pressing (when using rubber) to the pipes 4, 5 and 9 connected. In picture 2a the lower end of the pipe is through a pinch seal locked. This seal can be installed in a pipe that has already been pushed into the ground and thus enables an open pipe to be pressed in with less displacement work. The soil in the pipe is removed by lifting or flushing. The tube 4 can also be sealed by a potting compound at the bottom.
Bild 3 zeigt einen Wärmeaustauscher, in dem nur ein Rohr verwendet wird, das unten wie im Bild 2 oder Bild 2a verschlossen werden kann. Das Rohr wird durch eine Platte von der Länge des Rohres und der Breite des Rohrinnendurchmessers auf der gesamten Länge in zwei Kammern unterteilt. Am unteren Ende hat die Platte ein Loch. Oben befindet sich ein aufgeklebtes oder angepreßtes Verschlußstück 11 mit zwei Schlauchanschlußstutzen.Figure 3 shows a heat exchanger in which only one tube is used that can be closed at the bottom as shown in Figure 2 or Figure 2a. The pipe will by a plate the length of the pipe and the width of the pipe inside diameter Divided into two chambers along the entire length. At the bottom has the plate a hole. Located above a glued-on or pressed-on closure piece 11 with two hose connectors.
Bei Parallelschaltung von mehreren Wärme aus tauschern ist ein Verschlußstück mit je zwei Anschlüssen pro Kammer sinnvoll. Zur Verringerung des Strömungswiderstandes ist die Anordnung der Anschlußstutzen in Rohrrichtung vorteilhaft. When several heat exchangers are connected in parallel, a plug is required with two connections per chamber makes sense. To reduce the flow resistance the arrangement of the connecting pieces in the direction of the pipe is advantageous.
Die Platte 10 kann aus hochpolymerem, in der Sole etwas quellendem Material gefertigt werden. The plate 10 can be made of high polymer, which swells somewhat in the brine Material to be made.
Dies hat den Vorteil eines unkomplizierten Einbaus und einer guten Dichtung im Betrieb. Die Quellung kann durch Zugabe eines Quellungsmittels zur gebräuchlichen Sole erfolgen. Das Anschlußteil 11 wird mit einer Aufnahme für das obere Ende der Platte versehen und vor dem Einbau der Platte mit der Platte fest verbunden. This has the advantage of an uncomplicated installation and a good one Seal in operation. The swelling can be customary by adding a swelling agent Brine done. The connecting part 11 is provided with a receptacle for the upper end of the Plate provided and firmly connected to the plate before the plate is installed.
In diesem Fall hat die Platte kein Loch und ist soviel kürzer als das Rohr, daß nach Quellung der Platte unten eine Verbindung zwischen beiden Strömungskanälen bleibt. In this case the plate has no hole and is so much shorter than the tube that after swelling of the plate below a connection between the two flow channels remain.
Die unter Bild 2 und 3 beschriebenen Ausgestaltungen haben wirtschaftliche Vorteile, da nur das Rohr 4 aus relativ festem und damit im allgemeinen teurem Material sein muß.The configurations described in Figures 2 and 3 are economical Advantages because only the tube 4 is made of a relatively strong and therefore generally expensive material have to be.
Eine weitere sehr wirtschaftliche Ausgestaltung der Erfindung ist ein Wärmeaustauscher nach Bild 1 bis 3, dessen Hohlprofile aus relativ weichem und billigem, aber korrosionsfestem Material , z.B. aus Polyethylen- oder Polyvinylchlorid -Schläuchen bestehen. Um sie in das Erdreich zu bringen, wird zunächst ein Rohr aus-festem Material, z.B. mit Zahnung am unteren Ende, ins Erdreich gebohrt, das Erdreich im Rohr durch Heben oder Spülen beim Bohren oder nach dem Bohren entfernt und in dem festen leeren Rohr der Wärmeaustauscher niedergelassen. Anschließend wird das Rohr herausgezogen und der im Erdreich verbliebene Wärmeaustauscher mit wärmeleitendem und umweltfreundlichem Material verschlämmt.Another very economical embodiment of the invention is a heat exchanger according to Figure 1 to 3, the hollow profiles of which are made of relatively soft and cheap but corrosion-resistant material, e.g. made of polyethylene or polyvinyl chloride Hoses exist. In order to bring them into the ground, a pipe made of solid material is first E.g. with serration at the lower end, drilled into the ground, the ground through the pipe Lifting or flushing while drilling or removed after drilling and empty in the solid Tube of the heat exchanger settled. Then the pipe is pulled out and the heat exchanger remaining in the ground with a thermally conductive and environmentally friendly one Material silted up.
